Extension methods on a struct

Question

Can you add extension methods to a struct?

Answer 1

For future Googlers (and Bingers), here's some code to extend a struct. This example turns the value into a double type.

public static class ExtensionMethods {

   public static double ToDouble(this T value) where T : struct {
      return Convert.ToDouble(value);
   }
}

After this you can use ToDouble() like you use ToString(). Be careful on conversion items like overflows.
